PYROMELLITIC DIIMIDE COMPLEXES,THEIR PREPARATION,COMPOSITIONS CONTAINING THEM AND THEIR USE IN IMPROVING THE FEED EFFICIENCY OF RUMINANTS

摘要

Complexes of pyromellitic diimide compounds which are ruminant feed additives and which improve feed efficiency are disclosed. The pyromellitic diimide compounds may be unsubstituted pyromellitic diimide itself, or one of the nitrogen atoms may be substituted with an alkyl or substituted alkyl group. The pyromellitic diimide nucleus may also be substituted. The pyromellitic diimide compound is complexed with a compound containing an amide, amidine or thioamide linkage. The complexing agent may be either cyclic or open chain. Compositions using the complexes as ruminant feed additives are also disclosed.
